Application July 25, 1928, Serial No. 295,178 Renewed July 27, 1931 7 Claims.

My invention relates to furnace construction and refers more particularly to a furnace construction adapted to support or upon which a furnace wall may be hung.

One object of my invention is to provide a furnace framework of simple construction within which a complete furnace may be constructed.

Another object of my invention is to provide a furnace wherein the horizontal supports upon which the refractory blocks are suspended are adjustably held in spaced relation to each other and to their supports.

A further object of my invention is to provide a substantially hollow structure of fabricated steel adjustably holding a series of spaced shelves upon which may be hung a series of diamond shaped refractory blocks.

A still further object of my invention is to provide a unit or segmentally supported wall for furnaces wherein any of the refractory blocks comprising the said wall may be easily removed and replaced with another without disturbing the wall proper.

With these and other objects in view, I accomplish these results by the means shown in the accompanying drawings, which illustrate the preferred embodiment of my invention, wherein similar numerals refer to like parts throughout the several views, in which:--

Figure 1 is a horizontal section of a furnace, illustrating the application of the wall and structure to one type of furnace.

Figure 2 is a partial horizontal section of a furnace, taken on lines 2--2 of Figure 1.

Figure 3 is an isometric view of a clamp for adjustably holding the supports for refractory blocks.

Figure 4 is an isometric view, illustrating the application of the clamp shown in Figure 3.

Figure 5 is an isometric View of an adjustable chair adapted to hold a standard angle that may be utilized for supporting refractory blocks.

Figure 6 is an isometric view, illustrating the application of the chair shown in Figure 5.

Figure 'l is an isometric view of a standard structural shape that is slotted at the ends to provide for adjustment.

Figure 8 is a plan view illustrating the application of adjustable chairs wherein channels are used in place of I beams for the buckstays.

The furnace 1, is comprised of a front wall 2, a bridge wall 3, side walls 4 and 5, boiler tubes 6, bailles 7 and 8, drum 9, outlet to stack 10, cleanout opening 11, air box 12, and a burner 13, for any kind of fuel that may be desired.

The furnace is preferably built up of a series of vertical I beams or buckstays 14, suitably supported on the foundation 15, by the angles 16 and tied together at the top and other places that may be desirable by the channels 17, having angles 18, on the corners.

The diamond shaped blocks 19, utilized are of similar construction as those referred to in my application for patent dated July 21, 1928 and bearing the Serial Number 290,014, wherein the blocks are hung from supports and these blocks are preferably laid when desired with horizontal expansion spaces 20.

Outside of the buckstays 14, a series of doors 21, are detachably held by means of suitable clamps such as 22, and latches 23, so that there will be provided air spaces 24,, each having doors .or dampers, 25, hinged at 26, and the said air space may be connected at the most desirable place to a manifold 27, which may be provided with a pipe 28, for directing the preheated air that may be collected therein to some remote point where it may be utilized.

It is well known in the art that it is not possible to prepare refractory blocks for furnace use to definite or exact sizes, due to manufacturing difficulties and in view of this fact and constructive requirements, the block supporting means shown in Figures 3 to 8 inclusive, are made adjustable to suit these conditions.

Figure 3, illustrates a split, adjustable I beam clamp bracket 29, wherein the bracket proper is made up from an angular shaped plate 30, the small end 31, provided with a notch 32, and the large end 33, bent at right angles at 34, its outwardly turned part 35, is rounded at 36, to fit the flange of an I beam and intermediate between this flange and the notch is a hole for the bolt 37.

The clamp element of this clamp bracket is comprised of an angularly shaped piece 38, with a 95 hole. for the bolt 37, therein, bent at right angles at 39, and the end 40, rounded at 41, fits the flange of a standard I beam.

In Figure 4, the I beams 14, are shown in spaced relation to each other in the approximate position 100 that the parts would be arranged in actual use, illustrating the clamps 29, holding a pipe 42.

In Figure 5, the cast chair 43, with the flat back 44, provided with two slos 45 and 46, the upper end of which 4'7, extends outwardly formed to provide an angular pocket 48, the side adjacent the flat back 44, provided with two holes 49 and 50, adapted to receive bolts or rivets 51, and in Figure 6, there are two of these chairs 43, shown no in spaced relation to each other and holding the angle 52.

Figure 7 shows a standard bulb angle, a two flanged structural shape 53, bent at 54, at an angle of less than degrees, the outer flange 55, rounded at 56, being somewhat shorter than the flange 57, which is provided with two slots 58 and 59.

In Figure 8, two channels 60 and 61, are utilized back to back and spaced apart between which a bolt 62, may be utilized for adjustably holding the chair 43, thereon, the angle 52 being supported by these chairs and the doors 21, may be detachably held by means of the washers or plate 63.

It is obvious that the pipe 42, supported by the adjustable bracket 29, the angle 52, adjusfably supported by the chair 43, or the structural shape 53 adjustably mountable by its slots 58 and 59, are all adapted to hold refractory blocks such as shown in Figure 1, or illustrated in the application aforesaid bearing the Serial Number 290,014.

Having thus illustrated and described the preferred embodiment of my invention, I do not wish to limit myself to the exact construction or arrangement of parts shown, since it is evident that modifications may be made therein without departing from the spirit of the invention or scope of the claims.

I claim:-

1. A Iumace structure comprised of a series of buckstays in spaced relation to each other provided with adjustable base angle clamps, a horizontally arranged structural steel tie element at the extreme top thereof, a suitable number of horizontally arranged structural steel tie elements arranged in spaced relation to the extreme ends of said buckstays, a series of adjustable angular brackets mounted upon said buckstays horizontally holding a tube thereupon adapted to hold a series of upwardly sloping diamond shaped refractory blocks thereupon.

2. A furnace structure comprised of a series of buckstays in spaced relation to each other provided with base angles, a horizontally arranged structural steel tie element at the extreme top thereof, a suitable number of horizontally arranged structural steel tie elements arranged in spaced relation to the exireme ends of said buckstays, a series of angular adjustable chairs mounted upon said buckstays horizontally angularly holding an angle thereupon adapted to hold a series of diamond shaped upwardly sloping refractory blocks thereupon.

3. In combination, in a sectionally supported furnace wall construction, an outer shell or frame structure, a plurality of generally horizontallyextending support-means in vertically, spacedapart relation, vertically movable mounting means for securing the support means on said structure at variable heighs and means for fixing them in various positions of adjustment, whereby to carry or support wall sections of differing vertical heights, and an inner lining or wall of bricks sectionally carried on said support means, said sections of the inner lining or wall comprising horizon'ally-extending series of bricks.

4. In combination, in a furnace wall construction, an outer shell or frame structure, a plurality of generally horizontally-extending support-means in vertically spaced-apart relation, adjustable mounting means for securing the support means on said structure at variable heights, and an inner lining or wall of bricks sectionally carried on said support means, there being upper and lower face portions on said bricks angled with respect to the horizontal whereby gravity tends to hold the bricks laterally in place.

6. A furnace structure comprised of a series of vertical buckstays in spaced relation to each other, means for supporting said buckstays in position, a series of adjustable upwardly sloping bracke'. members mounted on said buckstays, said bracket members supporting a horizontal tube and a series of upwardly sloping diamond-shaped refractory blocks supported on said tube.
